Can anyone tell me what can I ferment that don't stink? I've done layer pellets and the finisher and after a few days., it smells like vomit and crap. I'm stirring twice a day and have an inch or so above the feed.I've tried with and without vinegar. I'm wanting to continue to do this inside with winter coming up and I don't have anywhere to put it where we won't smell it. I can deal with a sweet, sour smell but not what I'm smelling now. Thanks.
